6
http://base.thep.lu.se Original Goals Backend Production Experimental Data Biological / Sample Data + + Integrate: Publication Server Data Analysis Normalization
7
http://base.thep.lu.se To create a flexible and open software environment for a microarray lab (not just a database). Local database and analysis engine, not a public repository: Any experiment type (tumor profiling, timecourse, CGH, etc) Any array platform (cDNA glass, nylon, Affy, etc) Any scanner Any normalization algorithm Any analysis and data visualization technique No limitation on # of experiments Multi-user web server, individual access levels, Hyperlinks to relevant public databases (NCBI, etc) Very user-friendly point-and-click interface, follow natural biologist work-flow “MIAME supportive” (MIAME++) Extended Goals
8
http://base.thep.lu.se Details OPEN SOURCE under GPL Interface: Entirely Web-accessible, user-friendly User Accounts & defined Workspace and Projects User-level sharing of files, projects, and data Link to other databases (NCBI, UniGene, etc) Secure System Platform: Linux Operating System MySQL Database Apache Webserver PHP, C++ 1-2 Dedicated Servers Cost n/a Inexpensive
9
http://base.thep.lu.se Details “Plug-Ins”: Architecture for easy addition of your own normalization and analysis modules to BASE Proof-of-concept – we wrote 2 programs and plugged them in: Normalization (LOWESS, mean/median intensity) Multi-Dimensional Scaling (MDS) Import/Export: Import any data format using Import Wizard Export data in standard formats (ie Eisen cluster, J-Express, Expression Profiler, tab delimited, etc) MAGE-ML support soon

http://base.thep.lu.se Live Demonstration ER+ ER– Multidimensional scaling ER+ luminal cell type ER– basal cell type
12
http://base.thep.lu.se Future Directions MAGE-ML export support (limited import) Beta version available to interested groups Public final release to academia, open source, General Public License Encourage other labs to write and share their own normalization/analysis plug-ins Write more plug-ins Add new features in response to user-feedback
